Filter by:The purpose of this study is to test the effects of sleep and meal timing, independent of sleep duration, on glucose regulation and metabolic and hormonal control of energy balance in normal weight adults. This study will be a 4-phase, randomized controlled study of 5 days each in which participants will undergo 2 phases of late sleep times that differ in meal timing (normal or late) and 2 phases of normal sleep times that differ in meal timing (normal or late). The Aims and Hypotheses of this study are: Aim 1: To compare hormonal regulation of food intake and metabolic risk markers in response to altered sleep and meal timing. - Hypothesis 1: There will be an interaction between sleep and meal time on glucose, insulin, and glucose and insulin area under the curve after the glucose tolerance test such that the late sleep/late meal will result in the worst metabolic profile, normal sleep/late meal and late sleep/normal meal will have an intermediate profile, and normal sleep/normal meal will result in the best metabolic profile. - Hypothesis 2: There will be an interaction between sleep and meal time on leptin and ghrelin concentrations such that the late sleep/late meal timing phase will result in low leptin/high ghrelin, normal sleep/late meal timing and late sleep/normal meal will have an intermediate profile, and normal sleep/normal meal timing will result in high leptin/low ghrelin. Aim 2: To compare food intake over a 24-h period in response to altered sleep and meal timing. • Hypothesis 3: Energy and fat intakes will be greater during the late sleep timing phase compared to normal sleep timing.
Nocturnal seizure and Sudden unexplained death in epilepsy patients (SUDEP) are major concerns for parents and creates anxiety and poor sleep conditions for many families dealing with epilepsy. An accurate and reliable system for alerting parents to ongoing seizure activity could make a substantial impact in quality of life and possibly reduce the mortality of epilepsy. No previous studies in the pediatric population have been performed to evaluate this type of monitoring for seizure activity. This is one of the most common questions parents ask in clinic, "Are there any alarms that can tell me when my child is having a seizure at night?" Currently the answer is no. This study has the capability to give us data that may change this answer to yes.
While most of the research on integrated approaches of occupational health and safety and worksite health promotion to date has focused on manufacturing settings, employment is shifting to the service sector. Within this sector, health care employs over 12 million workers, and is the second fastest growing industry in the U.S. economy. In contrast to workers in other industries, rates of occupational injuries and illnesses among health care workers have increased over the past decade. The purpose of this study is to lay the foundation for integrated interventions in health care through examination of the associations of worker health outcomes and risks on and off the job with work policies and practices and to address the prevalent issues of musculoskeletal disorders (MSDs), particularly low back pain disability (LBPD), and health promotions through physical activity among patient care workers. The specific aims of this study are: 1. To estimate the efficacy and determine the feasibility of an integrated intervention, addressing both health protection and health promotion in order to reduce MSD symptoms and improve health behaviors among healthcare workers. We will assess between-group differences in MSD symptoms, health behaviors, including physical activity, and a set of secondary outcomes, including unplanned absence, reported injuries, worker compensation claims and costs, turnover and retention, intention to leave the job, and work-role function. This study will explore the working hypothesis that: Workers employed at baseline in patient-care units receiving the intervention will report greater reductions in their MSD symptoms (primary outcome) and greater improvements in health behaviors, compared with workers employed at baseline in units assigned to the Usual Care control group. 2. To determine the factors in the work environment which contribute over time to reductions in MSD symptoms and improvements in safe and healthy behaviors. (1) The work environment, work organization, and psychosocial factors, measured in our current study, will be associated with changes in workers' health behaviors and health outcomes between the assessments in the current and proposed studies; (2) Improvements in the work environment over time will be associated with improvements in workers' health behaviors and health outcomes. We will conduct multilevel modeling analysis to evaluate the simultaneous effects of worker-level and unit-level factors on MSD symptoms and safety and health behaviors.
The purpose of this study is to determine whether partial sleep deprivation, as compared with normal sleep, influences certain metabolic and cognitive parameters, related to food intake, hunger and memory functions, when participants are shielded from external time cues.
The study proposes to investigate whether acute total deprivation affects metabolism as measured through blood and peripheral tissues. Its aim is also to investigate how acute total sleep deprivation affects neurodegenerative markers, as well as hormones, memory performance and aspects of appetite regulation.
Background: - Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: - To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: - Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. - Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: - Participants will be screened with a medical history and physical exam. They will have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. They may have a spinal tap to collect cerebrospinal fluid. - Relatives will have a medical history and physical exam. They will also have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. - A relative s exams may reveal a behavioral or other disorder. If so, he or she may re-enroll on the study as a person with the disorder.
Presence/absence in bed along with heartbeat, respiration, and gross motion in bed will be measured in 48 Budd Terrace residents, a long-term care facility of Emory Healthcare. Measurement will be done using only pressure-sensitive mats that lie underneath the mattress and never touch the patient. PHI information will be collected by Emory staff. This PHI will be restricted to: age at time of participation; medical conditions; and medications. The PHI will be stored in a locked file behind a locked door. Data management will provide a unique identifier for each participant linked to a name that will be kept separately from the aggregate data. The data collected from the bed sensor will be processed offline and separately from the PHI to do proof of concept evaluation for the use of machine learning technology to predict bed exits 1 to 5 minutes ahead of time.
The objective of this research study is to assess the effects of music on patients' experience in the Intensive Care Unit (ICU). The hypothesis of this study is that patients who receive music therapy will report a reduction in negative recollections and experiences while on mechanical ventilation and will require fewer pharmacologic agents to maintain their sedation.
The primary objective of this preliminary study is to compare the Tennant BioModulator with Transcutaneous Electrical Nerve Stimulation (TENS) and Traditional Chinese Acupuncture for the management of chronic pain among injured service members. The secondary objective is to investigate any associative effects or benefits on sleep, Post-Traumatic Stress Disorder (PTSD) symptoms, or depression.
The primary purpose of this study is to test whether and how cognitive-behavioral therapy for insomnia (CBTi), a well-supported and highly effective insomnia treatment, may directly improve Posttraumatic Stress Disorder (PTSD) and Major Depressive Disorder (MDD) symptoms. The study is designed as a randomized controlled trial (RCT) to test the effect of CBTi on symptoms of PTSD and co-morbid depression prior to an evidence-based PTSD intervention and to assess the role of neurobiological processes and sleep architecture in mediating treatment outcomes.
